BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuum carrying a group of locking pieces. More specifically, the present invention provides:
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous body of a plurality of locking piece group carriers in which a number of locking pieces for locking a tag, a label, or the like to an article are supported in parallel with each other.

[0002]

2. Description of the Related Art A locking piece for locking a tag or a label to an article is composed of a plurality of locking pieces arranged in parallel with each other and supported and connected on a single directly-supported supporting rod. It is commercially available as a tab group carrier. Such a locking piece group carrier is mounted on a locking piece mounting machine, whereby each locking piece is cut from a connecting rod and driven into an article.

Generally, the above-mentioned locking piece driving operation is performed continuously on a large number of articles. Therefore, the locking piece group carrier provided in the locking piece mounting machine should have as many locking piece group members as possible. It is desirable to have.

[0004] The above-mentioned locking piece group carrier is manufactured by melting a thermoplastic synthetic resin, for example, a polyamide resin or a polypropylene resin, and injecting the molten resin into a mold.
This is carried out by cooling and solidifying and, if necessary, subjecting the solidified molded body to a stretching operation. In this case, the mold
It has a predetermined size and shape corresponding to the type and size of the molding machine, and in the mold, a plurality of locking piece group carrier forming cavities are generally formed in, for example, a V shape, an array, or a square shape. Is formed.

[0005] To increase the number of locking pieces per locking piece group carrier, the length of the support rod must be increased to support a large number of locking piece groups. However, if this is done, the length of the molding cavity in the mold naturally increases, making it difficult to uniformly inject the resin melt into the cavity, and further, changing the dimensions and shape of the mold. Is required. However, since the size and shape of the mold are determined by the molding machine to be combined with the mold, the change of the mold not only requires a large amount of cost per se, but also the design of the molding machine combined with this mold. This requires a change, which leads to problems such as a large cost, and it is practically very difficult to change the size and shape of the mold.

Therefore, in order to increase the number of locking pieces carried by the locking piece group support, two or more conventional locking piece group supports are bonded or fused in series at the ends of the support rods. Attempts have also been made to wear them. However, in such a connection method, it is difficult to firmly join the support rods so as to withstand the driving operation by the mounting machine, and the surface of the support rod connecting portion is smooth so that the inside of the mounting machine can be smoothly moved. It takes a lot of time and money to finish the work, and it is difficult to connect the support rods so that the distance between two adjacent locking pieces via the support rod connection part matches the regular distance. There is a problem that it is.

Therefore, it is possible to mold without changing the size and shape of the conventional mold, and to carry a larger number of locking pieces at a predetermined interval than in the prior art. There has been a strong demand for the appearance of a locking piece group carrier that can be smoothly driven by using the.

[0008]

According to the present invention, a larger number of locking piece groups are supported on a single continuous supporting means at a predetermined interval than in the prior art. An object of the present invention is to provide a locking member group carrying continuum that can be formed without changing its shape and that can be smoothly driven by using a conventional locking piece mounting machine.

[0009]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem by connecting a plurality of locking piece group carriers in series via a flexible hinge-shaped connecting portion having a specific shape and size. Is a successful one.

[0010] That is, the locking piece group carrying connection body of the present invention comprises:
One support rod composed of a substantially linear rod body, and a plurality of support rods supported on one side surface of the support rod and extending parallel to each other at a predetermined interval in a direction substantially perpendicular to the support side surface. And a plurality of locking piece group carriers, each of which is made of a flexible polymer material, wherein each of the locking pieces is in the length direction of the support rod. In contrast, a head and a horizontal bar extending in a direction substantially perpendicular to the
A filament portion connecting the head to the crossbar portion, and a connecting portion connecting the crossbar portion to the support bar, and the support bars are respectively adjacent to the filament portion. In a continuous body that is connected in series to mating support rods via a connecting portion formed therebetween, (A) the longitudinal axes of the adjacent support rods have a bend angle θ of less than 180 degrees with respect to each other. The crossing and the side surface of the support bar opposite to the locking piece group support side surface faces the inside of the bent angle, and (B) the end surface of the adjacent support bar is Cross each other at an angle of (180-θ) degrees,
And (C) the connecting portion is bendable between the end portions of the opposite side surfaces of the adjacent carrier rods across the intersection line of the terminal surface of the carrier rod. Characterized by being connected in a hinge-like manner.

[0011] In the continuation body of the locking piece group, end portions of the opposite side surfaces of the adjacent support rods following the connecting portion form inclined surfaces cut toward the connecting portion, respectively. May be.

Further, in the continuation body of the locking piece group according to the present invention, when the inclined surface is formed, a thickness T of the hinge-like connecting portion on a crossing line of the end surface of the supporting rod;
It is preferable that the depth D from the side surface opposite to the support rod to the intersection line satisfies the following relational expression (I): T ≦ 2D (I).

[0013]

As shown in FIG. 1 and FIG. 2, for example, a conventional retaining piece group carrier has one carrier rod 1 consisting of a substantially straight rod and one side of the carrier rod 1. And a large number of locking pieces 2 carried on each other. A large number of locking pieces 2 extend from the supporting side surface of the supporting rod 1 in parallel with each other at a predetermined interval in a direction substantially perpendicular thereto.

As shown in FIG. 2, each of the locking pieces 2 has a head portion 3 and a horizontal bar portion 4 extending in a direction substantially perpendicular to the length direction of the support rod 1, and this head portion. A filament section 5 connecting the section 3 and the horizontal bar section 4;
And a connecting portion 6 connected to the connecting portion 6. Part of this connection part 6 (preferably, a part adjacent to the horizontal bar part)
Is a thin portion 7 whose cross-sectional area is formed smaller than the cross-sectional areas of the other portions.
The locking piece 2 may be designed so that it can be easily separated from the support bar 1 at the narrow portion 7.

As shown in FIG. 3, for example, as shown in FIG. 3, a plurality of locking piece group support bodies having the above-described structure, The connecting rods 8 having a specific shape and size are formed between the ends of the adjacent supporting rods, which are arranged adjacent to each other at the ends, and are adjacent to each other via the connecting rods 8. Carrying rod 1
Are directly linked.

In such a continuous continuum of the locking piece group,
The pair of locking piece group carriers adjacent to each other has a direction in which the direction of the longitudinal axis 1a of the supporting rod 1 is less than 180 degrees, preferably 15 degrees.
Are arranged so as to intersect at a bending angle θ of degrees to 165 degrees. At this time, the retaining piece supporting side surface 1 of each supporting rod
b faces the outside of the bend angle θ, and the opposite side surface 1 c
Faces the inside of the bend angle θ. That is, since the two locking piece groups 2 extend outside the two support rods 1 arranged at a bending angle θ, these locking piece groups 2 do not come into contact with each other.

Also, the ends of the opposite side surfaces 1c (side surfaces facing the inside of the bend angle θ) of the adjacent support rods 1 following the connecting portion 8 are cut toward the connecting portion 8, respectively. An inclined surface 9 may be formed. Although there is no particular limitation on the angle between the inclined surface 9 and the opposite side surface 1c of the support rod 1, it is generally preferable that the angle be 45 degrees or less.

Furthermore, the terminal surfaces 10 of the support rods 1 adjacent to each other
Intersect each other at an angle of (180-θ) degrees and are continuous with each other at the intersection line 11. In general, it is preferable that each of the terminal surfaces 10 of the support rod 1 is at right angles to the longitudinal axis 1a of the support rod 1, but is not limited thereto as long as the above requirements are satisfied. When the end surface of one of the support rods is inclined at an angle of (90 + α) degrees with respect to its longitudinal axis,
The terminal surface of the other support rod is (90-
α) It is only necessary to incline at an angle of degrees. By doing so, when the end surfaces of the adjacent support rods are joined to each other, the longitudinal axes of the two support rods coincide, and the two support rods can form a straight line.

Further, a connecting portion 8 connects between end portions 9 (which may be the inclined surfaces) of the opposite side surfaces of the adjacent support rods.
Connects the end portions 9 on the opposite side surfaces of the adjacent support bars to each other in a bendable hinge shape across the intersection line 11 of the support bar end surface 10. Since such a hinge-like connecting portion is made of a flexible polymer material, it is bendable. Therefore, the supporting rods adjacent to each other have both terminal surfaces with the intersection line 11 of both terminal surfaces as an axis. It pivots until it joins with each other, and both support rods can extend in a straight line.

There is no particular limitation on the shape of the hinge-like connecting portion formed across the intersection of the two end surfaces of the adjacent support rods. For example, the terminal surface intersection line 11 of the hinge-like connecting portion 8
The surface 8a on the opposite side may form a plane straddling the intersection line 11 as illustrated in FIG.
As shown in FIG. 6, a curved surface or a bent surface protruding toward the intersection line 11 may be formed, or as shown in FIG. And may form a concave or curved surface.

In the connection of the support rods by the hinge-like connecting portion 8 as described above, if the end 9 of the opposite side surface of the support rod forms an inclined surface as described above, the support rods adjacent to each other are formed. The thickness T of the hinge-shaped connecting portion 8 on the intersection line 11 of the terminal surface 10 and the depth from the opposite side surface (the side surface on which the locking piece group is not carried) 1c to the intersection line 11 D preferably satisfies the following relational expression (I): T ≦ 2D (I).
It is still more preferable that the relationship of satisfies T ≦ 1.5D. When T and D satisfy the above relation (I), when the support rods adjacent to each other are linearly extended (FIG. 4), the top of the hinge-like connecting portion 8 is positioned on the opposite side surface of the support rod. 1c does not protrude excessively outside the level line, so that the hinge-like connecting portion 8 does not hinder the smooth movement of the locking piece group carrying continuum in the locking piece mounting machine, and The bending of the hinge-like connecting portion 8 is easily performed. T and D above
Although there is no particular limitation on the value of, it is preferable that T = 0.1 to 0.6 mm for a locking piece having a normal size.

When a plurality of locking piece group carriers are connected in series by the connecting portion, the locking piece closest to the connecting portion may include:
The distance P between the end face of the support rod and the distance P 'between the locking pieces preferably satisfies the relation of 0.4P'≤P≤P', and preferably satisfies the relation of 2P = P '. Is even more preferred. Generally, P 'is about 0.5 to 2.0 mm.

In the continuation body of the locking piece group according to the present invention, since the plurality of locking piece group carrier members constituting the continuity body are connected by a bendable hinge-shaped connecting portion, the bending angles θ are mutually set. Thus, adjacent carrier rods can be extended linearly as shown in FIG. At this time, the terminal surfaces 10 of the support rods adjacent at an angle of (180-θ) degrees
The support rods are turned around the axis 1 and joined to each other to stop the turn, so that the adjacent support rods do not bend further than 180 degrees. Further, the top of the hinge-like connecting portion 8 does not protrude excessively outward from the level of the side surface 1c of the support rod 1. Therefore, as shown in FIG. 4, the locking piece group supporting continuum of the present invention, which is linearly extended, smoothly moves in the locking piece mounting machine like the conventional locking piece group supporting body. be able to.
